EMG (biofeedback):

• Dual channel EMG.
• EMG range: 0.2 to 2000 μV RMS (continuous).
• Sensitivity: 0.l μV RMS.
• Accuracy: 4% of μV reading +/-0.3 μV at 200 Hz.
• Selectable band pass filter - 3db bandwidth.
• a. Wide: 18 Hz +/- 4 Hz to 370 Hz +/- 10% - reading below 235 microvolts 10 Hz +/-3 Hz to 370 Hz +/- 10% - reading above 235 microvolts.
• b. Narrow: 100 Hz +/- 5% to 370 Hz +/- 10%.
• Notch filter: 50 Hz (Canada 60Hz) - 33 dbs (0. 1% accuracy).
• Common mode rejection ratio: 130 dbs minimum @ 50 Hz.
• Work / rest periods: 2-99 seconds.
• Number of trials: 1-99.

 
STIM (neuromuscular stimulation):

• Dual channel stimulator.
• Amplitude: 0-90 mA into 500 Ohm load - actual mA will tend to be less than indicated due to electrode impedance at 1000 Ohms load (electrodes in poor condition) the maximum will be limited to 75 mA, at 1500 Ohms load the maximum will be limited to 50 mA.
• Type: constant current, maximum output voltage 70 volts +5 / -10 volts.
• Waveform: symmetrical, rectangular, bi-phasic with net zero DC current.
• Pulse width selection: 50-450 μS (2% accuracy).
• Pulse rate selection: 2-100 Hz (2% accuracy).
• Work / rest periods: 2-99 seconds.
• Time: 1 - 99 minutes.
• Ramp up time: 0.1 - 9.9 seconds.
• Preset and user programmable treatment programs.
• Automatic output shut off with detection of open electrode above 0.5 mA

 
Battery:

• 4 x AA, low battery indication at 5.4 volts +/- 0.2 volts, automatic shut off when voltage drops below the low indication. Replace the batteries immediately.
• The device goes off automatically when not in use (energy saving): for example when in settings and no key pressed over 1 minute, when in stimulation mode (home screen) and all channels are 0mA.
